Ibikoresho bya Solder kuri Laser Diode Bars: Ikiraro cy'ingenzi hagati y'imikorere n'ubwiringiro

Mu gushushanya no gukora laser za semiconductor zifite imbaraga nyinshi, laser diode bar zikora nk'ibikoresho by'ingenzi bitanga urumuri. Imikorere yazo ntishingira gusa ku bwiza bw'ibanze bwa laser chips ahubwo inashingira cyane ku buryo bwo gupakira. Mu bice bitandukanye bigize gupakira, ibikoresho bya solder bigira uruhare runini nk'aho ubushyuhe n'amashanyarazi bihurira hagati ya chips n'icyuma gishyushya.

1. Uruhare rwa Solder mu miyoboro ya Laser Diode

Udupira twa diode ya laser dukunze kubamo imiyoboro myinshi, bigatuma habaho ubucucike bw'ingufu nyinshi n'ibisabwa bikomeye mu gucunga ubushyuhe. Kugira ngo ubushyuhe bugerweho neza kandi bugakomera, ibikoresho byo gusoda bigomba kuzuza ibi bikurikira:

① Ubushyuhe bwinshi butuma ibintu bihindagurika:

Bituma ubushyuhe bukwirakwira neza uvuye kuri chip ya laser.

② Ishobora gutoha neza:

Bitanga isano ikomeye hagati y'urupapuro n'urupapuro rw'inyuma.

③ Aho gushongesha bikwiye:

Birinda kongera gutemba cyangwa kwangirika mu gihe cyo gutunganya cyangwa gukora nyuma.

④ Igipimo cy’ubwiyongere bw’ubushyuhe gihuye (CTE):

Igabanya ubushyuhe kuri chip.

⑤ Irwanya umunaniro cyane:

Byongera igihe cyo gukora igikoresho.

2. Ubwoko busanzwe bwa Solder yo gupakira Bar ya Laser

Ibi bikurikira ni ubwoko butatu bw'ingenzi bw'ibikoresho byo gusoda bikunze gukoreshwa mu gupfunyikamo utubari twa laser diode:

①Aloyi y'Ibumba rya Zahabu (AuSn)

Imitungo:

Ibigize Eutectic bya 80Au/20Sn bifite aho bishongesha 280°C; ubwiyongere bw'ubushyuhe n'imbaraga za mekanike.

Ibyiza:

Ituje cyane mu bushyuhe bwinshi, imara igihe kirekire inaniwe mu bushyuhe, idafite umwanda w’ibinyabuzima, kandi yizewe cyane

Porogaramu:

Sisitemu za gisirikare, iz'indege, n'iz'inganda zigezweho zikoresha laser.

②Indimu Yera (Imbere)

Imitungo:

Aho gushonga ni 157°C; byoroshye kandi byoroshye gushonga.

Ibyiza:

Ikora neza cyane ku bijyanye no gushyuha, ifite umuvuduko muke kuri chip, ikwiriye kurinda inyubako zigoranye, ikwiriye n'ibikenewe mu gufungana mu bushyuhe buke

Inzitizi:

Ishobora kwibasirwa n'umwuka uhumanya ikirere; ikenera umwuka utagira umwuka mu gihe cyo kuwutunganya, imbaraga nke za mashini; ntabwo ari nziza ku ikoreshwa ry'umutwaro mwinshi

③Sisitemu zo gusoda zivanze (urugero, AuSn + In)

Imiterere:

Ubusanzwe, AuSn ikoreshwa munsi ya chip kugira ngo ifatanye neza, mu gihe In ikoreshwa hejuru kugira ngo irusheho gukoresha ubushyuhe.

Ibyiza:

Ihuza ubwizerwe bwinshi n'igabanya stress, yongera uburambe muri rusange mu gupakira, ihuza neza n'ahantu hatandukanye ho gukorera

3. Ingaruka z'ubwiza bwa Solder ku mikorere y'igikoresho

Guhitamo ibikoresho byo gushongesha no kugenzura uburyo ibintu bikorwamo bigira ingaruka zikomeye ku mikorere ya electro-optical no ku buryo ibikoresho bya laser bigumana ubusugire bw'igihe kirekire:

Mu gihe cy’ingufu nyinshi zikomeje gukoreshwa, ndetse n’utunenge duto mu gusora bishobora gutuma ubushyuhe bwiyongera, bigatera kwangirika k’imikorere cyangwa kwangirika kw’ibikoresho. Kubwibyo, guhitamo gusora neza no gushyira mu bikorwa inzira nyazo zo gusora ni ingenzi kugira ngo hagerwe ku gupfunyika neza kwa laser.

4. Ingendo n'iterambere by'ejo hazaza

Uko ikoranabuhanga rya laser rikomeje kwinjira mu gutunganya inganda, kubaga, LiDAR, n'ahandi, ibikoresho byo gupfunyika bya laser birimo gutera imbere mu byerekezo bikurikira:

①Gusora mu bushyuhe buke:

Kugira ngo bihuzwe n'ibikoresho bikoresha ubushyuhe

②Solder idafite icyuma gifunga:

Gukurikiza amabwiriza ya RoHS n'andi mabwiriza agenga ibidukikije

③Ibikoresho bikoresha ubushyuhe bwinshi (TIM):

Kugira ngo hagabanywe uburyo bwo kurwanya ubushyuhe

④Ikoranabuhanga ryo gusora ibintu mu buryo buciriritse:

Gushyigikira miniaturization no guhuza ubucucike bwinshi

5. Umwanzuro

Nubwo ari ntoya mu bunini, ibikoresho byo gusoda ni byo by'ingenzi bihuza ibikoresho bya laser bifite imbaraga nyinshi kandi byemeza imikorere n'ubwizerwe. Mu gupfunyikamo utubati twa laser diode, guhitamo solder ikwiye no kunoza inzira yo guhuza ni ingenzi kugira ngo habeho imikorere ihamye igihe kirekire.

6. Ibyerekeye Twe

Lumispot yiyemeje guha abakiriya ibikoresho bya laser by’umwuga kandi byizewe hamwe n’ibisubizo byo gupfunyika. Dufite uburambe bwinshi mu guhitamo ibikoresho bya solder, gushushanya imicungire y’ubushyuhe, no gusuzuma uburyo bwizewe, twizera ko buri kuvugurura mu buryo burambuye bitanga inzira yo kuba indashyikirwa. Kugira ngo ubone amakuru arambuye ku ikoranabuhanga ryo gupfunyika laser rifite imbaraga nyinshi, twandikire.
